Let's divide 721789 by 65
We want to figure out the number of times 721789 can be divided by 65.

On to step 1:
When dividing 7 by 65, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 65

Moving on to step 2:
65 can be fit into 72 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 65 from 72 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 65

On to step 3:
71 divided by 65 is 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 65 away from 71, we end up with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 65

Step 4:
If we divide 67 by 65, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 111.0
Deduct 65 from 67 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 65

Moving on to step 5:
When dividing 28 by 65, we get 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 1110.0
If we take 0 away from 28, we end up with 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 65

Step 6:
The number 65 fits into 289 4 times, leaving a remainder of 29.
The next digit of our result is 4. 
Result so far: 11104.0
Deduct 260 from 289 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
The number 65 fits into 290 4 times, leaving a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 11104.4
Subtracting 260 from 290 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
65 can be fit into 300 4 times, resulting in a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 11104.44
If we take 260 away from 300, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 11104.44 and a remainder of 0.04.
